CLEVIS.

SPECIFICATION forming part of Letters Patent No. 237,447, dated February8, 1881.

Application filed October 9, 1880. (No model.)

To all whom it may concern:

Be it know that I, ALBERT SANFORD, of Oshkosh, in the county ofWinnebago and State of Wisconsin, have invented a certain new and usefulImprovementin Glevises; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figures 1 and 2 are views illustrating different forms of the invention.

Similar letters of reference in the several figures denote the sameparts.

My invention has for its object to provide improved means for effectingthe attachment of horses to plows, harrows, &c., whereby the power ofthe team is applied most advantageousl y, and the plow or other objectis enabled to be moved vertically and laterally, or turned partly orwholly over, without disturbin g the double-tree of the horses. To thisend the invention consists in the combination of two clevises and aconnecting bar or link, which is swiveled to one clevis and pivoted toand supported by the lugs of the other, as will be hereinafterexplained.

In the drawings, Figure 1, A represents a clevis formed with arms a. ain the usual manner, having perforations a a, in their ends for thepassage of the bolt, and also formed with lugs a? a which project inplanes parallel to the plane of the arms a to. These lugs a a are alsoperforated, and between them is inserted one end of a bar or link, 0,the same being held by a pivotal bolt, 0, as shown. The other end ofbarG is formed into a rounded shank, which, passing through alongitudinal perforation in a second clevis, D, is upset or providedwith a nut, 61, thereby forming a swivel-connection. Olevis D hasperforated arms d d and is provided with a bolt, d as usual. The clevisA is designed to be attached to. a plow or harrow by means of avertical.

bolt or pivot, and the clevis D is connected to the single or doubletree by means of the bolt d By placing the bar 0 between the twoclevises the plow or harrow is not only permitted to move horizontally,but, by reason of the swivel-connection, it can be turned on one,

side or completely over without disturbing the normal position of thedouble-tree.

The employment of the bar G, by shortcuing the length of the shank ofthe device, also lessens the liability of breakage by short turnlng.

Where the clevis that is secured to the plow is to be held by ahorizontal instead of a vertical pivotal bolt, the lugs of said clevis,instead of projecting in planes parallel to-the .arm s, as in Fig. 1 aremade to project in planes at right angles to the arms, as shown in Fig;2.

I claim as my invention-- The combination, with clevises A and D, eachhaving its securing-bolt, of the connecting-bar O pivoted between andsupported by the lugs 0t clevis A and swiveled to clevis D, whereby theplow, harrow, or other object attached to clevis A is enabled to turnlaterally or partly or completely over on joints between thesecuring-bolts of the two clevises, and without disturbing thedouble-tree attached to clevis D, substantially as described.

ALBERT SANFORD.
